Abstract :
This paper presents the concept of k-FR circuits. It is shown that all stuck-at faults and stuck-open faults in a k-FR circuit can be detected and located by k(k+1)+1 tests render the highly observable condition. K is usually two or three. The paper also presents an algorithm for converting an arbitrary combinational circuit into a k-FR circuit
